203. Action Potential

Life operates through precise molecular machinery. This simulation models biochemical reactions and molecular interactions at the cellular level.

About This Simulation

Create a Hodgkin-Huxley style action potential model with sodium and potassium currents.

Key Concepts

• Enzyme Kinetics: Enzymes catalyze reactions following Michaelis-Menten kinetics, with rates determined by substrate concentration and enzyme affinity (Km).
• Lock and Key vs Induced Fit: Enzymes recognize substrates either through rigid complementarity (lock-key) or conformational changes upon binding (induced fit).
• Allosteric Regulation: Enzyme activity modulated by molecules binding at sites other than the active site, enabling sophisticated metabolic control.
• Signal Transduction: Cascades of molecular interactions that amplify and transmit signals from cell surface to nucleus.

Why It Matters

Molecular understanding enables drug design, metabolic engineering, and synthetic biology.

How to Explore

• Adjust the sliders to modify simulation parameters and observe how the system responds
• Look for emergent patterns that arise from agent interactions
• Try extreme parameter values to find phase transitions and tipping points
• Compare the simulation behavior to real-world phenomena
